es6 javascript string interpolation - array within array

I have a json array that i get back from a ajax call. I loop over the data and append it to HTML , this works fine. Now I want to add the list of siblings as a list , which is an array item.family.siblings.

I have used string interpolation below with es6, how can i iterate through the list of siblings below, any suggestions?

     $.each(this.results, (index, item) => {
       let newitem = documment.createElement('div');

       newItem.innerHTML = `<div>
                                                      <span>Name</span><span>${item.name}</span>
                                                       <span>Father</span><span>${item.family.father}</span>
                                                      <span>Mother</span><span>${item.family.mother}</span>
                                                      <ul><span>Siblings</span>
                                                              <li>
                                                      </ul>
                                                       
                                             </div>`  ;

       this.listcontainer.append ( newItem)

     });

{  
  "results" : [
